PROBLEM TO BE SOLVED: To solve such problems that: a plant planted in a moss ball cannot be replaced watering requires a laborious, time-consuming method of dipping it for a certain period of time in a water-filled container large enough to accommodate the moss ball water may be collected on the lower surface of the moss ball and causes mustiness when the moss ball is put in a saucer and moss on the lower surface may be crushed and damaged.SOLUTION: A cup with a hole is embedded on the upper surface of a moss ball and a plant is planted in it. This enables the plant to be planted later or replaced, and watering from above. With a support made to jut out of the moss ball to make the moss ball float in air, no water will be collected on the lower surface of the moss ball, and this makes it less musty and keeps moss on the lower surface of the moss ball from damage.COPYRIGHT: (C)2014,JPO&INPIT【課題】苔玉に植えられた草木の植え替えが出来なかった。水やりは、苔玉が入る大きさの水の入った器に一定時間浸けておくという手間と時間のかかる方法だった。苔玉を皿に置くとき、苔玉の下面に水が溜まり蒸れる可能性あり、また下面の苔も潰され痛んでしまった。【解決手段】苔玉の上面に穴を開けたカップを埋め込み、その中に草木を植える構造とする。これにより草木の後植えや植え替えが可能となり上から水を掛ける水やり方法も可能になる。苔玉から支柱を出して苔玉を空中に浮かすことで苔玉の下面に水が滞留せず、蒸れが改善され、苔玉下面の苔も痛まない。【選択図】図1
